Deep rolling induces residual compressive stresses in the boundary layers At the same time through plastically shaping, the fatigue strength is increased and the surface smoothened. With certain limitations, residual stresses as well as dislocation densities are able to be specifically controlled through the process parameters and design of tool. For this reason deep rolling represents an efficient process for increasing the strength of highly stressed components.
